Why doesn't this statement work in the Shortest Path Problem example (spp.mod).
printf{(i,j) in E}"%11s\n", x[i,j];
I placed it after the minimize statement. Here is the error message..
Reading model section from spp.mod...
spp.mod:39: only numeric, symbolic, or logical expression allowed
Context: [ i , j ] ; printf { ( i , j ) in E } '...' , x [ i , j ] ;
MathProg model processing error
I'm just trying to get the stdout results of the model.
